Abstract

A lubricating grease delivery system of a coal mine rail transport cart comprises an oil reservoir and an oil pump. An outlet pipeline of the oil pump is divided into two branch pipelines via a tee joint, wherein an electromagnetic change valve, a manual operated three-position four-way change valve and an energy accumulator are sequentially connected on one of the two branch pipelines, an inlet and outlet pipelines of the manual operated three-position four-way change valve are connected with a compound hydraulic cylinder a, a lubricating grease reservoir is connected on the front portion of the compound hydraulic cylinder a; a first one-way speed control valve and a three-position four-way electromagnetic change valve are sequentially arranged on the other one of the branch pipelines; a lubricating grease outlet of the compound hydraulic cylinder a is connected with a one-way valve bridge, pipelines on two sides of the one-way valve bridge are respectively connected with a lubricating grease inlet and a lubricating grease outlet of the composite hydraulic cylinder b, and two limiters for limiting travelling distance of a piston are arranged on the front portion of a piston rod of the composite hydraulic cylinder b. Delivery of the lubricating grease is completed via alternating work of the two composite hydraulic cylinders. The lubricating grease delivery system of the coal mine rail transport cart has the advantages of small size, high pressure, large quantity of flow and stable work.

Description

technical field [0001] The invention relates to a lubricating grease conveying system, in particular to a lubricating grease conveying system suitable for coal mine rail transport vehicles in a low-temperature environment. Background technique [0002] Mine transport vehicles are widely used underground in coal mines to transport equipment, materials and even personnel. According to statistics, for a small and medium-sized mine with an annual output of about 700,000 tons, there are thousands of such mine transport vehicles in service. At present, for the lubrication of such low-speed and heavy-duty complete sets of equipment, lubricating oil should not be used for lubrication, but low-penetration grease with high viscosity should be used, but although low-penetration grease has good lubricating performance, but There is currently no equipment for delivering low-penetration grease. At present, manual grease guns or foot-operated mechanical greasers are widely used for greas...
